Macalister Irrigation District boundary

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from the Irrigation district administrative boundaries (polygons) mapped by Victorian water authorities based on geographic features. Input scales vary by water authority. The parent dataset(s) is identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.\n\n\n\nThe Macalister Irrigation District boundary.\n\n## **Purpose** \n\nThe Macalister Irrigation District selected from Irrigation district administrative boundaries (polygons) mapped by Victorian water authorities based on geographic features to define the area of interest in the report outputs.\n\n## **Dataset History** \n\nThe Macalister Irrigation District is part of the Irrigation district administrative boundaries mapped by Victorian water authorities based on geographic features. Input scales vary by water authority. The state wide irrigation districts (Irrigation District Department of Environment and Primary Industries GIP - )was the source dataset and the Gippsland Regional Model Extent (8e56c1ca-3fe9-4eb6-9ac0-75ba3f4058f8) was used to select certain polygons from the original using GIS software.\n\nAll boundaries are 1:100 000\n\nSourced from water authorities and Department of Primary Industries\n\nCurrent boundary as of 21 May 2012\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2006) Macalister Irrigation District boundary.

**摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）基于维多利亚州水务管理机构依据地理要素绘制的灌溉区行政边界（polygons）衍生而来。不同水务管理机构提供的输入比例尺存在差异。本元数据声明的谱系字段（Lineage field）中注明了其父级数据集，衍生数据集的制作流程则在本元数据声明的历史字段（History field）中予以说明。

麦卡利斯特灌溉区边界

**目的**

本数据集从维多利亚州水务管理机构依据地理要素绘制的灌溉区行政边界（polygons）中筛选得到麦卡利斯特灌溉区范围，用于明确报告成果中的研究兴趣区。

**数据集历史**

麦卡利斯特灌溉区属于维多利亚州水务管理机构依据地理要素绘制的灌溉区行政边界（polygons）的一部分，各水务管理机构提供的输入比例尺存在差异。本数据集的源数据集为全州灌溉区数据集（环境与初级产业部灌溉区GIP（Irrigation District Department of Environment and Primary Industries GIP）），并通过地理信息系统（Geographic Information System，GIS）软件，基于吉普斯兰区域模型范围（Gippsland regional model extent，8e56c1ca-3fe9-4eb6-9ac0-75ba3f4058f8）从原始数据中筛选出目标多边形。
所有边界比例尺均为1:100 000。
数据来源为水务管理机构及初级产业部。
当前有效边界更新至2012年5月21日。
